About Hélène
I help teams prototype fast, diagnose failing models and improve performance before production.
- rapid prototyping & proof of concept
- dataset analysis & model debugging
- performance improvement & architecture experiments
Ideal for teams needing technical reinforcement before industrialization.
🔍 Technical CV Audit & Model Diagnosis
When performance stagnates or results are unclear:
- dataset analysis & bias detection
- architecture & training review
- failure mode analysis
- targeted improvement strategy
📄 Deliverable: concise technical report + action plan.
⚡ Rapid Prototyping & Model Improvement
For early-stage or experimental work:
- quick POC pipelines
- architecture experiments
- dataset structuring
- performance iterations
📦 Deliverables: prototype models + experiments summary.
🛠 Technical stack: Python (PyTorch, TensorFlow/Keras, OpenCV, Scikit-Learn, Pandas/GeoPandas), Git, Docker, QGIS, CVAT, Blender.
